IMPROVEMENTV IN CAR-COUPLINGS.

Specication forming part of Letters Patent No.122,586, dated January 9,1872.

Specication describing a new and improved Car-Coupling invented byCHURCHILL EAS- TIN, of 'Louisville, in the county of Jefferson and Stateof Kentucky.

My invention consists in a self-coupling apparatus in which thecoupling-pin is suspended from a holder upon the top of the buffer, landis moved backward by alever to trip or release the link by lifting thelower end above the part of the buffer behind which it is locked when inthe working position, the said holder being moved up an inclined planeto lift the pin as it moves back. Two tripping-levers are used foruncoupling, one to be used by a person standing on the ground and theother when on the car.

Figure lis a plan View of a part of a car with myimproved coupling. Fig.2 is a longitudinal sectional elevation of the same; and Fig. 3 is afront elevation.

Similar letters of reference indicate corresponding parts.

A is the bu'er with a socket, B, in the end, which is iiarin g orbell-mouthed to receive the end of the link readily, and has a wide lip,C, hanging from the lower end of the mouth. The upper and lower walls ofthe socketed part of the buii'er are slotted, as shown at I) and E, andupon the upper wall an inclined plane, F, is providedeach side of theslot.l

G is the coupling-pin. It hangs by a spherical head, H, from a holder,I, in which it is confined by a cap, K, hinged to it and secured by aturn-key, L. This holder has an extension rearward behind the front endof the car, by which it is connected with the lever M pivoted to theframe at N and extending beyondone side of the car a short distance, asat O, for being taken hold of to disconnect the coupling. A spring, P,is connected at the other end for retracting it and throwing the holderI back to its normal position. With this lever the car is uncoupled bypulling the couplingpin holder back and up the inclines F until thelower end of the pin escapes over the upper edge of lip C at J and letsthe link escape. Besides this lever7 which is to be used by one personstanding on the ground, I propose to have another one, Q, so arrangedthat the uncoupling may be done by one on the car. This lever Q is fixedon an axle, It, that turns with it, and has an arm, S', inside of theend piece of the frame, and is connected to the end of the short arin oflever M by a chain, T, which being drawn over a guide-roller, U, whenlever Q is lifted, will vibrate the lever M, draw the pin-holder l back,and trip or disconnect the link.

The coupling is effected by the link being thrust in against the pin,and beyond, until the latter drops inside of the link and swings backagainst the lip C at J. For the protection of the lip the other Wallsrof the mouth, which are stronger, will be arranged to project slightlybeyond said lip, as indicated at m, Fig. 2.

Having thus described my invention, Iclainl as new and desire to secureby Letters Patentl. The combination of the swiveled couplin g-pin G,sliding-holder I, slotted draw-head, and inclines F, substantially asand for the purpose specified.

2. The combination of lever Q, axle R, arm S, chain T, lever M, slidingholder I, inclines F, pin G, and slotted draw-head A, as shown anddescribed, for the purpose specilied.
